    • PURPOSE: A net sinker for fishery is provided, in which lead is not contact with seawater by being inserted into iron barrel, thereby it does not cause submarine pollution. CONSTITUTION: A wire (4) is inserted into a barrel (1) horizontally through an insert hole (5) having a fixed diameter, and an injection hole (6) is formed at upper part of the barrel for injecting melted lead therein. The length of wire is determined according to the number of sinker (10). Melted lead (2) is injected into the injection hole after inserting the wire into the barrel.
    • 目的:提供用于渔业的净沉降片,其中铅通过插入铁桶不与海水接触,从而不会造成海底污染。 构成:通过具有固定直径的插入孔(5)水平地将线(4)插入筒(1)中,并且在桶的上部形成注射孔(6),用于在其中注入熔化的铅。 电线的长度根据沉降片(10)的数量确定。 熔丝(2)在将线插入筒体后注入注射孔。
